Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed May 10, 1918. Serial No. 233,694.

To all whom it may concern Be it known that I, ALBIN ANDERSON, a citizenof the United States, residing at Rockford, in the county of \Vinnebagoand State of Illinois, have invented certain new and useful Improvementsin Internal-Combustion-Engine Valves, of which the following is aspecification.

This invention relates to improvements in internal combustion enginesand it is the principal object of the invention toprovide an enginehaving a novel form of valve means associated therewith whereby to causethe intaking and exhausting of the fresh and spent gases to and from thecylinders of the engine; the construction of which is such as to reducenoise to minimum and to insure the proper functioning of the valve atall times, preventing the leakage of gas or the loss of compression inthe combustion chambers of the engine cylinders upon firing due tofaulty va ve seating.

Another and equally important object of the invention is to provide avalve of the character mentioned having means for cooling the sameduring operation thus Preventing overheating of the same, particularlyby reason of the heated exhaust or spent gases which pass therethrough;a continuous flow of cooling medium being maintained therethrough.

It is also an object of the invention to provide the valve with meansfor lubricating the same when in operation and consequently permittingfree movement thereof.

The foregoing together with additional advantageous details andarrangement of parts of the preferred embodiment of my invention will beclear from the specific description hereinafter contained, whenread inconnection with the accompanying drawings forming a part thereof whereinsaid embodiment of the invention is illustrated for the purpose offacilitating a full understanding of the said improvement. I

In the drawings: Figure 1 is a fragmentary vertical section through aninternal combustion engine having my improved valves applied thereto,Fig. 2 is a fragmentary horizontal section therethrough, and

Fig. 3 is a vertical section through one of the valves.

Having more particular reference to the drawings, in connection withwhich like reference characters will designate corre municating with theintake and exhaust ports 5 and 6 thereof, while pipes 7 and 8communicate with suitable ports formed in said valve receiving casings,the valve pipe 7 having connection with a suitable charge forming devicewhile the pipe 8 discharges into the atmosphere.

Fixedly mounted on a portion of the crank shaft 9 which extendslongitudinally through the crank casing 2 and journaled in suitablebearings therein is a pinion 10 adapted to mesh with valve actuatinggears hereinafter more fully described. For the purposcof illustration,I have shown in the accompanying drawings but one cylinder of aninternal combustion engine, it being understood, however, that the valveforming my invention may be used in connection with multiple cylinderengines and when so applied is operated in the same manner hereinafterdescribed. A piston 11 is slidably arranged in the engine cylinder 1 andis pivoted with a rod 12 having connection with one of the offsetportions of the crank shaft 9, while to ignite the explosive charge inthe firing chamberof the cylinder I apply an ordinary type of spark plug13.

Slidable in the cylinders 3 and 4 are the improved valves, designated bythe numerals 14 and 15, said valves being tubular and having ports 16extending diametrically therethrough and adapted to be intermittentlyalined with the ports in their respective cylinders. In this connectionit will be noted that the exhaust valve 15 has the port 16 lined withasbestos or other suitable heat insulating material. Rods 17 arepivotally engaged with the tubular valves and extend downwardly intoengagement with certain of the offset portions of longitudinallydisposed erank shafts 18 mounted in suitable hearings in the ends of thecrank case and arranged substantially parallel with the crank shaft 9.As will be noted, the inner surfaces of the tubular valves 14 and 15 areformed with longitudinally disposed ribs or fins 19, while a series ofopenings 20 are formed in the opposite sides thereof and 7 whichcommunicate with conduits 22 extending into engagement with the chargeforming-device of the engine whereby a suction will be created in saidcylinders. In this connection, it is to be noted that openingsdesignated by the numeral 23 are formed in the casing of the engine at apoint adjacent the crank case thereof and serve to permit the inflow ofair which is in turn drawn up.- wardly into the cylinders 3 and 4 byreason of the suction occurring therein.

It is to be noted that the engine is pro-- vided with the usual coolingmedium circulating jacket whereby the temperature of the same will bemaintained at the properdegree and hence, perfect functioning of thesame is insured. 1 H

As means for imparting rotarymotion to the crank shafts 18 and to causeoperation of the several valves 14 and 15 at predetermined intervals toeffect the intaking and exhausting of the fresh and spent gases to andfrom the engine cylinder, gears 24 are mounted on saidcrank shafts andmesh with another gear 25 mountedin suitable bearings on the edge ofcrank case and. having connection with the pinion 10 carried by thecrank shaft 9. As will be noted, the relative size of the gear 'and thepinion is such as to cause the proper timing of the valves with theirrespective ports.

In operation, upon rotation of the crank shaft 7 the piston 11 is movedin the cylinder to accomplish. the usual intaking, com-.

pression, Working and exhausting strokes, the several valves 14 and 15operating in a manner to cause the alining of their respective portswith the'ports of the cylinders 3 and 4 and the cylinderl at intervalsto effeet the intaking and exhausting of the fresh and spent gases toand from the same. By reason of the connection of the valves 14:

will be moved upwardly into 'alinement with the ports 5 and 6 and uponcontinued rotation of said crank shaft will be immediately moveddownwardly and disalined therefrom, thus affording an exceedingly quickvalve action which, as will be appreciated, is essential in multiplecylinder engines. By reason of the connection of the cylinders 3 and 4with the charge forming device of the engine, a suction will be createdtherein and consequently a cooling draft of 'air will be at all timesmaintained through the tubular valves 14 and 15, including thelongitudinally disposed ribs or fins 19 and keeping them at the propertemperature. The valves are lubricated by the ordinary splash system,the crank shafts 18- thereof dipping into the lubricant and splashing aportion of the same on to the walls of the cylinders 3 and 4, which uponmovement of the valves into engagement therewith will be evenly appliedover the same, the superfluous lubricant passing through the openings 20and downwardly through the valves back into the crank case.

Manifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claims,I consider within the spirit of my invention.

I claim:

In combination with an internal combustion engine having intake andexhaust ports in the cylinder thereof, valve cylinders adjacent saidengine cylinder and communicating therewith and having air inletopenings adjacent their lower ends, open ended tubular valves slid'ablein the valve cylinders and adapted to intermittently establishcommunication'between the valve and engine cylinders, longitudinallyextending ribs formed within said valves, and heads for the upper endsof said valve cylinders having air outlet openings formed thereinwhereby a conduit for communicating with a charge forming device mayhave communication with the valve cylinders.

In testimony whereof, I aflix my signature hereto.

ALBIN ANDERSON.
